Dale (#4), you make good points. I would add that Keith’s first sentence: “IF you look at this article then CO2 needs to make up 2% of the total ice volume to weaken it.” is not even true.

Pertaining to Keith’s comment #1: CO2 levels in atmosphere are rising much faster than Keith claims. They are rising almost 2ppm per yr not decade. And local concentration particularly in North have been measured 400ppm.
If I’m not mistaken rise of CO2 at past extinction events was on order of ppm per century or thousand year period not yearly events as we have created by burning up Earth’s easy to get at sequestered carbon for energy or enabler of consumer lifestyle.
Also In Keith’s error of logic about ‘impossibility’,'ONLY’ and
Affinity of ice surface for CO2 could raise expressed harm to strength of the material and raise bubble concentration.
Error of logic and oversimplification and down right fabrication of untruth don’t often happen in isolation but rather in groups that tend to play off each other for support.. It is hard to counter grouped errors in short fashion. But somethings need doing sometimes.. Even if stressful.. Even if it seems futile. But thee is a quote by Einstein who said things need to be expressed as simple as possible not simply simple.. Saving Earth needs clarity.

1700 billion metric tons of CH4 lays in methane ice and as free gas in sediment on shallow sea floor of East Siberian Arctic Shelf vulnerable to heat increase and disturbance. Let’s hope the weakening of water ice bonds with CO2 rise of atmosphere isn’t going to have destabilizing effect on methane ice better known as methane hydrate. I like the comparison of the way CO2 facilitates weakening of water ice to that of rust or corrosion of metal. Let’s hope the land based ice masses of Greenland and Antarctica resist decay.
Let’s hope the world wakes up to the present danger and acts.
Let’s create an open system of human endeavor to match Nature.. Let’s make an adjustment by tapping writ of law known as ‘Act of God’ so value of money reflects value of its use toward goal of keeping Earth alive. -People too.

“It’s well established that, in the years to come, increasing amounts of carbon dioxide in the air will cause the climate to change, thereby leading to the ice caps melting at an accelerated rate and worldwide sea level rise. ”

It’s hard to take seriously an article that starts with the above sentence.

IF you look at this article then CO2 needs to make up 2% of the total ice volume to weaken it. This is impossible to do considering CO2 in the atmosphere is only 395 PPM. It is ONLY increasing at 2 PPM every ten years! By the time it could increase even to 450 PPM at this rate then Crude oil AND natural Gas will have severely declined in production or will have become a luxury item only used by a few countries. Even easy to mine coal will have been exhausted. There will be 12 billion people by then cooking with firewood again. Geologically speaking Human Culture as we know it will wink out in a flash, WAY before higher Ocean levels are going to be an issue.
